【摘要】 针对以往关于中国能源替代问题的研究未考虑价格扭曲因素的不足,本文以超对数成本函数为基础,对中国工业部门要素价格扭曲进行测度,并计算要素自价格弹性及要素间替代弹性。研究发现,能源的相对价格存在严重扭曲;能源自价格弹性在2004年前为正,其原因是价格管制与市场不完善阻碍了其调节功能的发挥;资本与能源间并不存在确定的替代关系,劳动与能源间在近期表现为替代关系,而其他投入与能源间表现为互补关系。本文最后根据实证研究结果提出三点政策建议。更多还原

【Abstract】 Aiming at the neglect of price distortions in current research on factor substitution in China,this study,based on a generalized translog cost function,firstly estimates the distortions in relative price of factors and then measures the own-price elasticities and the substitution elasticities of factors in Chinese industry.Findings indicate that:(1) There is substantial distortion in relative price of energy.(2) The own-price elasticity of energy is positive before 2004 because of administrative control and market imperfections,which tend to prevent the price from functioning within the market system.(3) The substitution elasticities show the substitution between capital and energy is uncertain,labor and energy are substitute in recent years,the other input and energy shows complementarity.The study finally proposes three constructive suggestions for the policy on energy price and energy efficiency in China.更多还原
